I think you mean 9x12 envelope.
To send a standard letter from California to Georgia, you would need one first-class stamp. If the letter is heavier or larger than standard, additional postage may be required. It's always best to check with the postal service for the most accurate postage rate.

It only takes one for the first ounce. For additional weight, you will have to add additional stamps. Usually four sheets of paper in an envelope will need an extra stamp.

depends on the size and weight Right now stamps are 44 cents for every 10 pages of a normal Business Letter envelope. So if this is 10 pages and LESS you will need one 44 cent stamp. If it is more you will want to put extra stamps on it. Best thing to do take the letter to the post office and mail it if you can they will weigh it and give you an exact accurate weight to mail it. As long as it is in a business envelope, long envelope and not a manila envelope or box. It is that for 10 pages or LESS 44 cent stamp.
